Insights+ Key Biosimilars Events of September 2022

  • Biosimilars are developed to be highly similar versions of approved biologics in terms of safety, purity, and potency
  • Biosimilars are expected to be a cost-effective alternative to the high-priced branded biologics, offering significant and much-needed cost savings to both payers and the patients
  • During the month of September, Fresenius Kabi’s Stimufend (biosimilar, pegfilgrastim) received the US FDA's approval for non-myeloid malignancies, Sandoz reported P-I/III (ROSALIA) trial results for Biosimilar Denosumab to treat postmenopausal women with osteoporosis. Our team at PharmaShots has summarized 16 key events of the biosimilar space of September 2022

1. Fresenius Kabi’s Stimufend (biosimilar, pegfilgrastim) Receives the US FDA Approval for Non-Myeloid Malignancies
